The research based metabolic and blood pressure targets that the national service framework for diabetes in England and Wales will set in the implementation document will be impractical for use in routine clinical care: targets need to be tailored to the individual patient, according to Peter Winocour

The publication of the national service framework for diabetes in England and Wales will raise public awareness of diabetes throughout the United Kingdom. Its recommendations are influenced by evidence that adverse vascular outcomes may be reduced by tight control of blood sugar and blood pressure1^–3 and that secondary prevention of macrovascular disease is feasible through modification of dyslipidaemia and use of antiplatelet agents4^–7^w1; and by the recognition of an estimated doubling in incidence of diabetes over the next 10 years.8

This has led to the production of guidelines for optimal care that may be incorporated into a nationally recommended standardised approach, with targets for metabolic and vascular variables and recommendations for certain therapies.9^–11^w2 The effectiveness and quality of healthcare systems are increasingly being measured by how well such standards are adhered to, and it is therefore vital that the targets are appropriate. The following discussion focuses on type 2 diabetes, since this is much more common than type 1 diabetes.
